[TenTec] Corsair II PTO Problems

[Steve Berg]

I am now the proud owner of a Corsair II and external VFO. (Thanks again 
Jay!)  I have never had a rig with a PTO, and this one has two of them. 
   Everything else I own uses variable capacitors or digital encoders to 
tune them around the bands. I have been advised that these need 
occasional rebuilding, and this was mentioned prominently in the eham 
reviews.  How do I know when the PTO needs rebuilding?    What do I need 
to look for in the way of symptoms?  So far, I have had a great time 
with the rig on CW, including working a KH7 on 80 meters with my humble 
ground mounted vertical antenna. Sure never thought I would ever be 
doing that here.
